CAL MAG MAX 7-0-3 With 4% Calcium and 2% Chelated Magnesium
 Cal Mag Max is a Growth Products’ fertilizer with the power punch to serve plants with calcium, magnesium, and a kick of NPK. This product breaks the barriers between fertilizers and micronutrients, giving you the best of both. Cal Mag Max contains the perfect 2 to 1 ratio of calcium to magnesium. The calcium and magnesium are 100% chelated with a special sugar-acid chelate. Cal Mag Max works faster and is less wasteful because it is completely available as a foliar or soil drench. Use Cal Mag Max as a supplement, and in alternate feeding with a standard fertilizer.

Green Industry professionals wage a constant battle to correct Calcium (Ca) and Magnesium (Mg) nutrient deficiencies that occur in plants. Symptoms of calcium and magnesium deficient plants include:

  • Immature development and deformity of the plant.
  • Calcium deficiencies most often occur in the newest growth of a plant. The leaves and new tissue of the plant will curl, twist, and eventually fall off.
  • When a plant is deficient in magnesium, it is the older, more established leaves that are first affected. The plant will become chlorotic, with the leaves changing color beginning as a reddish brown and changing over to yellow. The end result is that the leaves curl and eventually drop off of the plant.

To prevent and correct these deficiencies, a 2-to-1 calcium-to-magnesium ratio product is most often recommended. Growth Products' Cal-Mag Max (7-0-3) fertilizer with 4% chelated calcium and 2% chelated magnesium fits the bill perfectly. It is quick-acting and easy to use.

Cal-Mag Max is great for all classes of horticultural plants, including ornamentals, trees, shrubs, plants, turfgrass, etc.. When applied as a foliar spray, it provides almost immediate correction of calcium and magnesium deficiencies. Cal-Mag Max can also be applied to the soil, as a supplement or in alternation with other fertilizers.

Got it when they couldn't
In stock and fast shipping was the selling point. My local auto parts stores didn't have this in stock anywhere. I got it in two days and cheaper than they could get it to me. Fits great and works like it should. I'm on top of my maintenance for all my vehicles, so it will get changed on time. Life span should not be an issue.
